RECORDING-SCALE.

SPECIFICATION forming part of Letters Patent No. 627,978, dated July .4, 1899. Application filed September 15,1897. Serial No. 651,815. (No model.)

To all whom, t may concern.-

Be it known that I, JEREMIAH CAMPBELL, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and` useful Improvement in Recording-Scales, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature. i

The invention is an improvement upon that described in my Letters VPatent No. 544,207, dated August 6, 1895, and No. 558,630, dated April 21, 1896; and it relates especially to the coupling together of the counterpoise andthe recording devices, wherebythe movement of the counterpoise causes the movement of the recording devices, and whereby also the counterpoise may be used independently of the recording devices in weighing.

1t also relates to means whereby the Vrecording devices are centered in respect to the printingtype andvcounterpoise during the printing or recording operation.

It further relates to means for obtaining two recording-impressions by the use of one typeribbon.

It also relates to means whereby a single lever controls the counterpoise-latch yand the connection between the counterpoise and the recording devices.

In the drawings, Figure 1 is a View in side elevation of scaleshaving the features of my invention. Fig. 2is a view in side elevation, enlarged, of a portion of the scale-beannthe counterpoise, and the recording devices. Fig. Sis a view in vertical section upon the dotted line 3 3 of Fig. 2. Fig. 4 is a view principally in vertical section, showing the connection between the counterpoise and the recording devices. Fig. 5 is a detail view in plan of the counterpoise. Fig. 6 is a view in vertical section upon the dotted line 5 5 of Fig. 5.

The scale preferably has the tare-beam A and tare-counterpoise A,the main scale-beam B and main counterpoise IB', and the stationary track C below the main scale-beam, upon which are mounted to slide lengthwise the recording devices C. The scale-beam B has the notched upper edge Z) and upon its lower edge the line of inverted numerals b', from which recording -impressions are taken, substanlifted from engagementl with the notch by the l lifting-pin h6 on the lever-shaft 57. (See Fig. 6.) vThe counterpoise also has at its front end b3 the sight-pointb9,which is in line'with the latch. The counterpoise also carries a short bar or auxiliary scale-beam E, upon which a small counterpoise Ev is Iadapted to be moved, this beam and counterpoise weighing smaller fractions or weights than the larger counter-poise. The short beam E is not notched,land the small counterpoise E' is moved back and forth thereon by a knob e. It is centered in respect to the recording devices during the printing operation, as will hereinafter appear, andv has a line E2 of inverted numerals upon its underside which are'in line with the numerals of the scalebeam.

The recording devices C have the two parts or sections c c, and the part c is movable vertically upon the part c by a cam-lever c?, as described in my said Patent No. 558,630. The recording device is connected with the countei-poise by a'vertically-movable connection F in the nature ofga bolt. It is carried by the counterpoise, and its weight forms a part of the weight of the counterpoise. It is moved downward by the counterpoise-latch lever b3 and upward bythe counterpoise-latch spring b5 and also by a coil-spring surrounding it. (See Fig. 4.) The upper partfof the connection is contained in a guiding-sleeve f', and it is connected with the counterpoiselatch lever by a rock-shaft f2, supported at f3, the arm f4 of which engages the upper end of the sliding connection and the arm f5 the counterpoise-latch lever b3. The end of the last-nam ed arm f5 has aslotf, into which a pin f7, extending from the side of the countcrpoise, projects and plays. The lower end of the sliding connection E has the tapering surfaces f8 and fg. The bolt or connection is represented as engaging the upper plate of the vertically-movable section c' of the record- IOO line over lroll d3 to the second reel. brings over the platen cG the same ribbon, but

ing device, the saidplate having a hole c3 of the size of the main part of the boltor connectien.

Upon actuating the counterpoise-latch 1e ver to disengage its registering-latch b2 in order that the counterpoise may be slid upon the scale-beam to another lposition the connection or bolt F is moved downward and engages the section c' of the recording device, so that the movement of the counterpoise also causes the movement of the recording devices. When the counterpoise has been located in its new position and latched, its latehing-lever returns to its highest position, thereby allowing the bolt or connection to be lifted by'itsspring to 'its highest position and `to become practically disengaged from the reeording-devices,- although its pointedcndl still yre'r'nains'in the hole c3'in plate'c4, thereby causingits inclined'or tapering ends to remainin such relation vto *the recording devices that they `may Aact as centering 'devices'for' them asthe'section c'fis lifted to thetype on the scale-beam andfsmall counterpoise to Vprint an impression of'theweight.

Iltwill he understood that'the -small counterpois'eearries afshortk type-.bar with inverted numerals, as intthe case of'mypatents above. If'therecording devicesarefnot inline with thefparticular numeral whose po' referred to.

sition fthe=main counterpoise indicates, itis upon-:its upward movement centered in respect itofsaid'numeralby contact of one edge or ther'f the'hole with one or the other of thein'clined or -tapering ends of the locking connection. rIlhe small counterpoise is at the thebottom ofthe counterpoise.

-The-piinting-ribbon is'carriedfby the reels DiD, which are operated as described in my said Patent '-No. 558,630, but which arefarranged'with their axes lengthwise the recordingdevice instead of crosswise it, as-in said patet,-an`d-the ribbon extends 'from one reel overa small antifriction-roll d uponthe plate cforward toa-small antifriction-roll d on'` the plate eiland then vbackward upon the same This inftwo thicknesses'folded upon it to run in opposite'directionfs, thereby providing two printing-sections, the upper ofl which is adaptledftofprin't upon the continuous recordingstrip-which extends from the reel H to the reel H', and3 the lower of which is adaptedto press upon arecording ticket or slip inserted over theplate c4 upon the platen between the platen andthe'printing-section of the ribbon. The

continuous'recording-strip is fed as described inV mysaid YPatent No. 558,630.

Y "Thezoperation of the device is as follows: The tarefhaving been determined, the'main counterpoise is moved upon the main scalebeam, as in ordinary weighing, its latch being held lifted from the notches, and a connection between the counterpoise and the recording device being established at the saine time by thelifting of the latch, the counterpoise and recording devices are simultaneously moved. Vhen the counterpoise has reached its balancing position, its latch is allowed to engage the proper notch, and by said engagement the connection betweenv the counterpoise and the recording devices'is established, so that the counterpoise is free to actas a counterpoisesimply and without being hampered or restrained by the weight of the recording devices or any part thereof. The smaller counterpoisefis then movedto establish the accurate balancing of the main 'counterpoise, land `by lso vdoing its rtype-'barfis moved and the 'numeral whichindicates'the weight which itis set to'brcught inlinewith the-numeral expressing the weight'tofwhi'ch the main counterpoise is set. The'upper section of the frecording'device is then moved upward and is centered and' locked infre'lation to the main counterpoise, anditiserves to'c'enter and lock' the same counterpoise,=and an impression bythe numerals'indic'atingthe Weight is printed upon the lrecording-istrip and alsoupon a supplementalfticketfor strip at the Sametime, if desired.

rPhe recording-'strip and the println g-ribbou are fed bythe meansdescribed in'myfsaid patent; but any other suitable means maybe employed for feedingfthem.

I prefer that thefrecordingdevices be incased in a casing whichiprovidesfanopening for' the insertion of the ticket or slip, butwhich covers the recording-strip 'andthe-recording IOS devices, which4 case may be`locked,if desired,

sothat access to the recording-strip may not be had by the weigher.

Having' thus fully describedmy invention, I claim-and desire to secure by LettersPatent of the'fUnited Statesl.
